VALVE.`

SPECIFICATION forming part of Letters Patent No. 505,792, datedSeptember 26, 1893.

Application filed .Tune 27, 1892. Serial No. 438,224. (No model.)

To a/ZZ whom it may concern,.-1

Be it known that I, EDWIN C. HENN, a citizen of the United States,residing at Bloomfield, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inValves, of which the 1following is a full, clear, and exact specifica-Ion.

The invention relates to theclass of straightway check or back pressurevalves having a removable disk, the objectbeing to provide a simple,cheap, light and strong valve of this class having interchangeableparts, in which the disk, that will set tightly and securely every timein the same position against the seat, can be quickly and accuratelyinserted in position or removed therefrom for the pur pose of cleaning,repairing or renewing; and to this end the invention resides in a valveconsisting of a body having ports, disk chamber, and seat, with ears orlugs on the body extending into the disk chamber, a bridge to which thedisk is pivoted supported Vby the lugs, dowel pins or studs removablysecuring the ends of the bridge toV the lugs, and a cap to cover anopening into the disk chamber, as more particularly hereinafterdescribed and pointed out in the claim.

Referring to the accompanying drawings Figure l is a plan, with the capremoved. Fig. 2 is a longitudinal section; and Fig. 3 is a transversesection of a valve embodying the invention.

In the views l indicates the body which is cast to shape of any commonmetal, as iron, brass or bronze, in the usual manner, with the pipe ends2 which may be flanged, belled or screw-threaded as shown for connectingthe valve with the system in which it is to be used; a cap end 3 for acap 4 that may be taken o for inserting or removing the disk; a diskchamber 5, and a seat 6 around one of the ports.

Usually cast integral with the side walls of the body on the interior ofthe disk chamber, are ears or lugs 7 which are perforated, bored ortapped to receive dowel pins-or studs 8 that are riveted, screwed orotherwise firmly secured to the lugs so as to project upward from theirtop surface.

Extending across the chamber from side to `side and `resting on the lugsis a bridge 9 having perforations or sockets that receive and fit thedowel pins on the lugs, so that `when Vthe bridge isplaced in positionthe pins pass into the perforations and hold the bridge securely andaccurately in place.

Projecting from the bridge are ears l0 which can be readily machined toexact gage and bored to receive the pivot ll that bears the swinging arml2 to which is secured, usually by a screw and nut., a disk 13 havingits face formed and adapted to it closely against the seat when thevalve is shut.

`VVhen the bridge is placed upon the lugs the dowel pins center as wellas hold it and insurelthat it will remain in the exact position for thedisk to shut correctly against the seat, in which position the bridge issecurely held by the cap when the latteris secured in place over the capend of the body.

To remove the disk the cap is unscrewed and the bridge lifted from thelugs, it readily sliding off the pins. Thevalve is strong as there areno openings through the walls, therefore can be made light in weight,the parts can all be readily machined and the dowel pins cheaply securedto the lugs on the body so that the bridge which can be accurately andcheaply bored for the purpose will slip easily upon the pins and be heldin exact position each time so that the parts are made interchangeableand the valve always shut tight.

I claim as my invention- A valve consisting of a body having pipe andcap ends, a disk chamber and seat, with two ears projecting from theside walls of theV body into the disk chamber, a narrow bridge extendingacross the chamber, with its ends resting upon the ears,small guidingand holding pins projecting from one part into the other to temporarilysecure the ends of the bridge to the ears, an arm pivoted to the bridge,a disk secured to the arm, and a cap held upon the cap end,substantially as specified.

EDWIN C. HENN.
